I just sent off my dome port to Amphibico to replace the plexiglas..they has some mark on it, which for sure isn't from bumping coral. I previously had not know the front cover itself was replaceable.

It is odd how I never see sharks diving in the Philippines....we're going to try to change that with something in Malapascua where pelagic thresher sharks come to be cleaned, but they do not get close in such clear water like your shot.

That is always the catch-22 of shooting and diving-if the water is crystal clear, there is not enough food in the water to support filter feeders, whereas if there is, then like the Philippines, the density of soft corals and other filter feeds is bewildering.

That sure would rock to get such tiger shark footage, you must have been stoked!
